The role of Sentinel Lymph Node Biopsy(SLNB) among mutation-negative BC patients is well established; however, we are lacking data to assess the role of sentinel lymph node biopsy for patients who are undergoing surgery for prophylactic reasons without proven malignancy. Literature has reported a positive Occult Breast Cancer (OBC) rate of 0 to 11.3% among mastectomy specimens which are removed prophylactically. Majority of the time when the invasive focus is diagnosed in prophylactic mastectomy specimens they are found to be in-situ cases where axillary Staging using SLNB can be exempted; however, when the OBC is identified even in prophylactic mastectomy specimens, axilla should be addressed accordingly. Albeit SLNB has associated complications with it; postoperative pain, lymphedema, paresthesia and rare reaction to the injected dye. Therefore the question here arises regarding skipping SLNB among patients who are undergoing PRRMs without proven malignancy pre-operatively. However, before standardizing the practice in our population we need convincing evidence that the frequency of OBC is low among our patients. By identifying the true prevalence of OBC among our gene-positive HBC patients who are opting for PRRM, we would be able to skip SLNB; as not only it has psychological implications but also adds a financial burden on patients and families due to the addition of an extra procedure and hospital bills; as the financial and socioeconomic status of our population has already declined over last few years due to the economic crises faced worldwide, specifically after-affects are seen in Lower Middle-Income Country(LMIC) like Pakistan.
